Hi Marek,

There are a few patchsets under review that are using trace events
in CXL. I'm working on one for CXL Poison Retrieval.

There is also tool support, the monitor patchset, making its way
upstream for ndctl that uses the trace events.

I haven't looked at lttng.

Can you share more about your project?

Thanks,
Alison
